Abstract

This study aims to determine the contamination of coliform bacteria in drinking water sources of residents in Malang City. Type of this research is explorative descriptive research. The study population was all drinking water sources of residents throughout Malang City, while the research sample was 15 residents wells in five subdistricts of Malang City with each sample taken three sample points. The samples were tested using 3M petrifilm E. coli/coliform count plate. The results showed that all the samples studied were contaminated with coliform bacteria with the highest percentage of 23.01% for E. coli bacteria contamination and 15.41% for total coliform bacterial contamination with an average of bacterial colonies 200 colonies.

Abstract

Fern is cosmopolitan plants which are almost scattered in all parts of the world, one of which is found in Baluran National Park and in Malang. The potential and benefits of these ferns are quite important for agriculture and medicine because of the chemical compounds they have, especially in Pteris vitatta L. This study aimed to analyze secondary metabolites contained in P. vittata L. in Baluran National Park, Situbondo and in Malang. The samples used were leaves and rhizome P. vittata extracted using methanol 96%, followed by a qualitative test of the content of alkaloids, flavonoids, terpenoids, polyphenols, tannins, saponins, using phytochemical screening methods with several reagents. The results showed that the leaves and Rhizome P. vittata L.. in Baluran National Park, Situbondo were positively containing secondary metabolites of terpenoids, polyphenols, tannins, saponins, and alkaloids (Dragendorf and Bouchardat reagents), whereas flavonoids were not present in all samples. However, the results of P. vitatta L. phytochemical screening around Malang State University positively contained flavonoids, polyphenols, terpenoids, alkaloids (Wagner and Dragendorf reagents). The difference in results from these two places is because the secondary metabolite content in plants is affected by stressful environmental conditions such as soil texture where it is grown or is affected by the precursors of the secondary metabolites of the metabolites.

Abstract

Cellulolytic bacteria are bacteria that have the ability to hydrolyze cellulose complexes into smaller oligosaccharides and eventually become glucose. Glucose is used as a carbon and energy source for bacterial growth. This study was conducted to isolate the cellulose degrading bacteria from banana peel compost that produce cellulose enzymes based on the clear zone that visible around the colony. The cellulolytic activity was determined by the ability of bacteria to hydrolyze the Carboxymethyl Cellulose (CMC) substrate. Determination of cellulolytic activity is known based on cellulolytic index calculation, the diameter total minus the diameter of the colony and divided by the diameter of the colony. The result of five bacterial isolates was found but only one bacterium had the potential to be a cellulose degradation. Based on the Microbact Gram-Negative Identification System, the bacterium is Burkholderia cepacia. These bacteria have an important role in nature as decomposers of various complex compounds, such as cellulose, hemicellulose, lignin, and pectin.

Abstract

Phytoplankton plays an important role in the aquatic ecosystem for supporting the survival of organisms, such as zooplankton and fish. The aim of this research was to observe the phytoplankton in the common carp ponds and tilapia ponds with water quality parameters at IBAT Punten, Batu, East Java. The survey method was used in this research. The water quality assay was temperature, brightness, pH, DO, CO2, Nitrate, and Orthophosphate, and the phytoplankton analysis was phytoplankton abundance, diversity index, dominance index, relative abundance, similarity index, and evenness index. The water quality on the carp ponds and tilapia ponds was quite good for common carp and tilapia growth. The average of phytoplankton abundance in common carp ponds were 1538 cell/ml which classified oligotrophic and tilapia ponds were 4900 cell/ml which included mesotrophic respectively, diversity index was moderate in both ponds, no dominance specific phytoplankton in both ponds the relative abundance in both ponds showed different phytoplankton availability, the similarity, and evenness index showed the same in both ponds and evenly on tilapia ponds and equally on common carp pond respectively. The carbon dioxide (CO2), nitrate, and orthophosphate have a strong correlation to phytoplankton abundance with value 0.882; 0.949; and 0.967 respectively. In the future, pond management will be needed in IBAT Punten with growing natural food.

Abstract

The population growth in Indonesia experiencing a very high development, causing population density. This study aims to know about environmental conditions, the density of population and waste disposal in Malang city and effect between population density and types of landfills. The method was an observational study using observation, questionnaire and closed interview guidelines. The results of this study were (1) the environmental conditions categorized good, (2) the average population density is 175,814 people per square km, (3) 63.33% respondents road throw domestic waste and not processed. (4) the population density variable does not influence the type of waste disposal.
